March 5, 2009 was a thrilling solar term and also entered the "99". When the "shock" arrives, it means that the temperature will continue to warm up, the spring thunder will start to sound, and all kinds of hibernating animals that lie in the mud will be awakened, and the underground insects will start to wake up. At this time, the climate has two major characteristics. One is that the temperature rises faster; the other is that the spring thunder sprouts or the spring thunder begins to scream, so it is called horror.
"Spring is thundering, everything is long", China has attached great importance to thrilling and solar terms since ancient times. Many agricultural activities will start from this, and the most important agricultural thing is "the next seedling". During the horror season, the season of rice breeding is entered. As the saying goes, “Half a good wokâ€, in order to obtain high yield of rice, we must first cultivate a sufficient number of strong seedlings, and fertilization in Putian is an important measure to cultivate strong seedlings.
The purpose of rice fertilization management is to cultivate strong seedlings. The basic characteristics of rice seedlings are: the seedlings are strong and straight, the leaves are bright, the leaves are bright green, the base is "flat", the roots are developed, the white roots are more, and there are tillers. For the early and middle-aged rice, the age is short, the temperature during the breeding period is low, the soil nutrient release and the rate of fertilizer decomposition are slow. Fertilization should pay attention to the application of fermented and degraded high-quality farmyard manure, and then apply the fertilizer to make the base fertilizer. . In principle, the application of chemical fertilizers should control nitrogen fertilizer. For the paddy field with higher soil fertility, less nitrogen fertilizer should be applied, and the amount of phosphate fertilizer and potassium fertilizer should be increased appropriately. That is, the compound fertilizer with low nitrogen, high phosphorus and medium potassium should be used for breeding, and high nitrogen compound fertilizer should not be used for seedling; Fertilization of calcium phosphate or calcium magnesium phosphate fertilizer 30-40 kg) and potassium fertilizer (10 kg of potassium chloride application); in high-fertility soil, the fertilizer can be applied to the fertilizer in the field, and nitrogen fertilizer is applied to the general fertility soil. About 3 kilograms. This can reduce the possibility of rotten rice in the field, and is conducive to the cultivation of strong. In the field of zinc deficiency in the soil, 1 kg of zinc sulfate per mu is mixed with organic fertilizer to make the noodle fertilizer of Putian. The method of using zinc fertilizer must be applied evenly. In the late stage of Putian, 3-4 days before the hoeing, the nitrogen fertilizer can be applied as a fertilizer to the body.
In late rice field fertilization, the temperature and mud temperature are relatively high. In order to prevent the seedlings from growing too much, the late rice field is more suitable for fertilizer efficiency and slow and lasting farmyard manure. At the same time, the application rate of phosphate fertilizer is slightly less than that of early and middle rice fields. Calcium 25-30 kg or calcium magnesium phosphate 25-30 kg. Potassium fertilizer is very important for late rice breeding. Potassium fertilizer can prevent flax leaf spot and brown spot disease of the seedlings, and it is better to apply 8-10 kg of potassium chloride per mu in the late rice paddy field. Nitrogen application should pay more attention to the application of less or no nitrogen fertilizer to control the growth of seedlings. 4-5 days before transplanting, 2-3 kg of urea or 8-10 kg of ammonium carbonate per mu should be applied to ensure the good development of new roots after transplantation and accelerate the regreening of the seedlings.
The amount of fertilized rice in the hybrid rice field should be slightly more than that in the conventional rice field, and attention should be paid to the reasonable combination of nitrogen, phosphorus and potassium and the nitrogen application, especially paying attention to the application of potassium fertilizer. Because potassium has a good effect on hybrid rice, it is advisable to apply 10-15 kg of potassium chloride per mu as a noodle fertilizer.
